"Oh
man, these things are so trick. I used them on all my motors
at the Snowbirds. The brush looks like it has been run for
a couple of runs and it is so smooth. The motor is extremely
efficient and the power is perfect right from the get go. I
noticed that the wear on my 9x1 in touring car was less, I
usually have to cut the motor every run for best performance
but the fussy brush whatchamacallit was keeping the comm more
clean and I could run easily two times without discoloration.
This is a great tool and should be in everyone's tool box,
I just don't see how the heck you came up with the design,
it is so trick."

| "Hello
I would just like to say that I received the fussy brush today
and we put it to the test. We have all of our motors saved
on the dyno from after a fresh rebuild. We spun up a few motors
that had a run or two on them and got some new numbers, then
we used the fussy brush on them and spun them up again and
our smallest gain over a fresh rebuild was 1.2 watts and our
biggest was 3.4. This is by far the most remarkable tool that
I have. The person I was dynoing these motors with went and
ordered one right away (you'll see there is another order from
central Illinois) Thanks very much for the timely shipping
and for a great product." |

have been using the FussyBrush's religiously on all my motors.
I am seeing less comm wear, longer brush life and more consistent
performance." |

If
your tired of using up your time and commutators seating
brushes then this is your solution. Our Brush Shapers & Serrators
are both fast and accurate. This tool will shape full face
or serrated brushes while inside the motor can. This means
it will accommodate for all of your hood alignments.
If
you've ever tried re-shaping laydown to standup or standup
to laydown then you know it is really impractical to do
on the motor commutator. Problem solved. Shapes serrated,
regular, slotted, timed, drilled or any other configuration
to the internal specifications of your motor.

Two
Styles & Four sizes available. Our original plan was to
offer sizes by the 1/100th inch but found there was such a
small difference in the size that the motors would seat the
difference in seconds. What we ended up with is 0.285" & 0.300" for
regular commutators and 0.335" & 0.350" for large
commutators. These four sizes are available in both Full Face
smooth cuts and Serrator Cuts.

The bits fit
over the end of the shaft and are held in place by the spring
tension when you put the endbell on. There is a stainless steel
spring pin to keep the bit locked to the main shaft. Inside the
bits is a 60 degree concave shape that fits over a 60 degree
convex shape on the shaft. This helps to keep the bit centered. |
| "Got
a set of shapers from you. I don't know how to start. Well, I
was really excited when I received them and saw how they worked.
After reading the instructions, it seemed straight forward to
use them. Last weekend I ran mod (Reedy T1s). First run I had
new brushes and comm cut. Ran the first heat of qualifying, it
feels the same as I normally find on my car. But in the second
heat, cut the comm again but this time I prepared the brushes
(729) with the shaper. This time, don't know what happened...I
had so much more power. Unbelievable. I did it again for the
3rd heat, I got faster. My lap times are very consistent and
it gets faster and faster. This tool of yours is doing a great
job. No more motor break-in on stands. I can get my motors ready
for action in less time than I used to. Before, sometimes I would
even skip the motor break-in as time was tight. Now I have all
the time I need and know that my brushes and motor will perform
for me. Thanks for the great product." |

"Not
only is your customer support outstanding, but the product
is awesome. It saves us tons of time at the track and is
just plain easier to use, not to mention the tools drop
right in my pit box."

Brush Hood
Alignment - As your shaping your brushes the alignment of your
brush hoods becomes really obvious. You can see this when breaking
in brushes the old way with the comm, it just takes longer. |
| "I
am not a motor expert, but I do understand the basics. It's really
nice when all you have to do is reassemble a motor and go, with
no break-in nausea. Additionally, the shaper is saving me money,
in that I am re-using the same brushes more times. I cut my stock
motors every three runs, and I have just been shaping the brushes
lightly at rebuilds (other than when I put in new brushes which
get the full treatment). Also, the shaper is great for aligning
brush hoods - for alignment purposes alone, the shaper is worth
the money. The bottom line is that my motors have gotten noticeably
faster, while I am putting in less effort and time working on
them. Thanks for the great product!" |

Here
you can see how it installs. Really simple. The spring is there
for stability without having to shim to your motor. With full
face cuts you can turn by hand without the pinion but serration
cuts do require a pinion for grip. I have a piece of shrink wrap
installed over the pinion but it's not needed. You don't need
to install the springs. It's faster to just apply a little pressure
to the brush with your endbell philips screwdriver. Full face
cuts require about the same as spring tension and serrations
require a little more. |

Reedy
KR 12 x 1 Brushes seated with Fussy Brush FB-350. Notice the
brush shavings and how the brush face is dull, not glazed. That
dull finish is softer and dissipates faster, keeping a fresh
brush face longer as you race. |

Commutator
wear on a brand new Reedy KR. I don't know about you, but I get
a little upset when I have to cut a new commutator to repair
the damage from breaking in the brushes. Yes, I did use low voltage,
and yes, I did drop the timing back. You get commutator damage
breaking in brushes even if you use a drive motor. Another problem
solved. Let's say you go through 8 sets of bushes for the life
of the commutator. Even though you only have to skim the comm
to get rid of this, that's 8 less times you have to skim it. |

use the 285 unit at least two or three times a week. Honestly,
I don't know how I ever got along without it. You folks should
be quite proud of your products." |

"DeWayne,
As you know from my original letter to you I was impressed as
hell with the fussy brush. Well I have to admit
and I don't know how you will take this, but thru my many times of using
the fussy brush at the track I have had terrible
success. There was too many times that after the heat races and placing
in the A main that I would go thru the motor and pull out my best battery
and get ready for the race, and then Pow. too much power, I don't know
how many times I did that, you
would guess that a guy would learn after a bit but when you have the tools,
you need to use them. Well the bright side
is it will make a better driver out of me. So in ending you should feel
guilty because I'm sure that I am not the only one
that has had to compensate because you just had to make a quality product,
and then on top of that we have to deal
with unsurpassed customer service......How dare you!........Dewayne, if
no one else says this to you then shame on
them,,,,,,,,, THANK YOU!!!!!!! Please do keep me in mind for future products." |
